Abstract

Stroke is a common multifactorial disease, and the third leading cause of death worldwide, which results in serious long-term mental and physical disability among survivors. The role of affected triglyceride metabolism in the development of ischemic stroke is under extensive investigations. Here, we examined three SNPs, rs12130333 located within the ANGPTL3 locus; rs16996148 residing at the CILP2 gene locus; and rs17321515 at the TRIB1 locus, which were originally reported in association with decreased triglyceride levels; therefore, we investigated their possible protective effect against the development of ischemic stroke. A total of 459 Caucasian stroke patients, stratified as large-vessel, small-vessel, and mixed stroke groups, and 168 control subjects were genotyped using PCR-RFLP methods. As a result, we could not detect any differences in triglyceride or total cholesterol levels in relation to any allelic variants of rs16996148, rs17321515, or rs12130333 SNPs. No correlation was found between the minor alleles rs16996148-T (P = 0.881), rs17321515-G (P = 0.070), or rs12130333-T allele (P = 0.757) and the risk for development of stroke. The data presented here suggest different scale of effect of triglyceride modifier alleles and also their variable susceptibility or protective nature.
